🛒 Ingredients
For the Cake
- 1 box white cake mix
- Ingredients called for on the cake mix box, such as eggs, oil, and water
For the Coconut Cream Filling
- 1 (3.4 oz) box instant coconut cream pudding mix
- 2 cups cold whole milk
- 1 (14 oz) can sweetened condensed milk
- 1 teaspoon coconut extract
For the Frosting
- 1 (8 oz) container whipped topping, thawed
- 4 oz cream cheese, softened
- ½ cup powdered sugar
- 1 teaspoon vanilla extract
For the Topping
- 1 cup sweetened shredded coconut, toasted
- ½ cup white chocolate chips, melted
- Maraschino cherries, optional
👩🍳 Instructions
1. Bake the Cake
Prepare the white cake mix according to the package directions.
Pour the batter into a greased 9×13-inch baking pan and bake according to the recommended time and temperature on the box.
Once baked, remove the cake from the oven and allow it to cool completely.
2. Prepare the Coconut Cream Filling
While the cake cools, whisk the instant coconut cream pudding mix with the cold whole milk until it begins to thicken.
Add the sweetened condensed milk and coconut extract. Whisk until the mixture is smooth and creamy.
Refrigerate the filling until you’re ready to assemble the cake.
3. Prepare the Frosting
In a large bowl, beat the softened cream cheese with the powdered sugar and vanilla extract until smooth and creamy.
Gently fold in the thawed whipped topping until everything is evenly combined and fluffy.
Keep the frosting refrigerated until needed.
4. Add the Coconut Filling
Once the cake has cooled completely, use the handle of a wooden spoon or the end of a large spatula to poke holes throughout the cake.
Make the holes fairly deep but avoid going all the way through the bottom of the cake.
Spoon the coconut cream filling over the cake, spreading it evenly so the creamy mixture can soak into the holes.
5. Frost the Cake
Spread the cream cheese whipped topping evenly over the entire cake.
Use a spatula to create soft swirls across the surface for a pretty, homemade finish.
6. Add the Toppings
Sprinkle the toasted shredded coconut generously over the frosting.
Drizzle the melted white chocolate over the top. For an extra festive presentation, add maraschino cherries just before serving.
7. Chill and Serve
Cover the cake and refrigerate for at least 2–4 hours before serving.
For the best flavor and texture, chilling overnight allows the coconut cream filling to soak beautifully into the cake.
Slice, serve chilled, and enjoy every creamy, tropical bite!
⭐ Tips for Success
Toast the coconut: Toasting brings out a deeper, nuttier coconut flavor and adds a delicious crunch.
Cool the cake completely: Don’t add the filling or frosting while the cake is warm. Heat can make the creamy layers too soft.
Use cold milk: Cold whole milk helps the instant pudding thicken properly.
Chill before serving: This cake becomes even better after several hours in the refrigerator as the flavors blend together.
Melt the white chocolate carefully: Heat it gently in short intervals, stirring between each one, to prevent scorching.
🥥 Optional Variations
For an even stronger coconut flavor, sprinkle additional toasted coconut between the cake and frosting layers.
You can also add chopped macadamia nuts for a tropical crunch or use coconut-flavored whipped topping if available.
For a chocolate-coconut version, drizzle the finished cake with melted milk or dark chocolate instead of white chocolate.
Want a more colorful presentation? Add pineapple tidbits, toasted almonds, or extra maraschino cherries before serving.
🧊 Storage
Because this cake contains dairy-based filling and whipped topping, it should be kept refrigerated.
Cover tightly and store in the refrigerator for up to 3–4 days. Keep the cake chilled until you’re ready to serve it.
